As already mentioned, the ascendant querent is Volume is conjunct Chiron, which shows the suffering this situation is causing.
As I stated earlier, I prefer the modern assignation of the 4th and 10th, whereby the father would be the 10th house, ruled by Saturn. We know he is up in age, the father figure, and sad, all of which corresponds to saturn.
Saturn is near the beginning of his 2nd house, and co-ruler of the house, which gives us an idea of what his concern is about. Money.
Saturn had been conjunct expansive Jupiter, ruler of his 3rd, which made him quite optimistic, maybe too much so. Jupiter is also the ruler of intercepted Sagittarius, the gamer, in his 12th house of self-undoing.
Saturn next will square Uranus, co-ruler of his 2nd of finances, and located in his 5th of short term investments and gambling.
We also find aggressive mars in aries on his 5th cusp. Exaggeration. Mars separates from the square with pluto of compulsion and co-ruler of his 12th of hidden matters.
Note that conjunct the cusp of the 10th, Volume’s father, we find sun, who rules his 8th of other people’s money, loans, pensions and mortgages.
I asked Volume why she had entered the asteroid Varuna in the chart. Of all the thousands of asteroids to choose from, why this one?
A summary of its symbolism is “Astrologically, Varuna represents law and order, the sea, and the lasting legacy one leaves behind.“
Varuna assumes importance in the chart because Saturn, ruler of the 10th, approaches an opposition.
So the general picture would seem to be that of worries about an investment gone sour, and the repercussions it might have on his home and family (Chiron conjunct his 4th, which is the radical 1st).
Some of these positions and aspects could also reflect a love affair, but what puzzled me is the Saturn position in the father's 2nd house, which all falls into place if we consider that he is not having an affair, but is worried about a money situation.
